ALEXANDER T. STEYTART, OF PHILADELPHIA, PENNSYLVANIA.

SAFETY-RAZOR.

Application filed January 24, 1921} T 0 all whom it may concern:

Be it known that I, ALEXANDER T. S'rnw- ART, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Safety-Razors, of which the following is a specification.

This invention relates to safety razors and it has for its primary object to provide a device in which the blade proper conforms substantially to that of a double edged 1101- low ground razor whereby increased strength and durability are attained.

Another object of my invention is to pro vide a safety razor characterized by a novel form of spring adjustment whereby the closeness of the shave may be accurately adjusted according to particular tastes.

A still further object of this invention is the provision of a safety razor comprising few and simple parts that are not liable to get out of order and which is cheap to manufacure and exceptionally durable in use, one blade only being required and that of a nature easy to reset or strop.

lVith the foregoing and other objects in view as will later on be more apparent as this description proceeds my invention consists essentially in the novel features of construction, combination and arrangement of parts hereinafter fully described and more specifically defined by the appended claims.

In the further disclosure of the invention reference is to be had to the accompanying sheet of explanatory drawings constituting a part of this specification, and in which like characters of reference designate the same or corresponding parts in all the views.

Figure 1 is av vertical longitudinal section through a safety razor embodying my invention.

Fig. 2 is a top plan of the same.

Fig. 3 is a fragmentary side elevation of the upper portion of my improved safetyrazor with part broken away and in section to show the underlying structure.

Fig. 4; is a detail perspective view of the razor proper; and I Fig. 5 is a section on the line 5-5 in Fig. 1.

Referring more particularly to the views my improved safety razor comprises a frame or body portion 10 of appropriate material which is fashioned or molded to provide reversely rolled portions 11 the longitudinal Specification of Letters Patent.

Patented Oct. 25, 1921.

Serial No. 439,480.

edges whereof are formed comb-like or toothed at 12 to serve as a seat for the razor designated generally by the numeral 13. it the back of the aforesaid frame or body portion 10 there is integrally formed a handle portion 14 preferably octagonal in cross-section as shown by Fig. 5, and said. handle portion has an axial passage or bore lo'extending therethrough terminating in a 11p 16 at its inner end for the purpose later on explained. in the space intervening the rolled portions 11 is a flat spring 17 which is flexed to normally occupy the position shown by the dotted lines in Fig. 3 and it is also formed with outwardly turned or bent ends 18 which are centrally notched at 19, and said spring 17 is held firmly in place by flaring or expanding the lip 16 over a hole 20 axially central thereof as will be clearly comprehended on an examination of the drawings.

The razor 13 is preferably of the cross section shown that is to say it substantially conforms to and provides opposed integral hollow-ground blades 21 which in use repose on the aforesaid comb-like edges 12 of the rolled portions 11, and longitudinally of the central portion of said razor I provide opposed ribs 22, 28, conveniently of the shape shown, the latter of which 23 is adapted to engage in the notched out parts 19 of the flat spring 17 when the parts are assembled and thereby correctly position the blades 21 relative to the edges 12 when the parts are assembled, as well as prevent the razor 13 from lateral movement or accidental displacement.

In order to provide ameans for looking or securing the razor 13in place I employ a tubular stem 24 of a diameter to be freely rotatable in the bore 15 of the handle 14, said stem being fashioned at its outer end with a fluted or serrated head 25 whereby it can be easily manipulated, and at its inner end I form a threaded extension 26 which is adapted to be screwed into a cor respondingly threaded hole 27 provided for the purpose central of the razor. It is to be here noted that the lower rib 23 is cut away at 28 to permit the inner end of the stem 24 being properly manipulated until the shouldered end 29 is brought into abutment or close juxtaposition to the main or body portion of the razor 13. Ears or ribs 30 are also provided on the comb-like Seated longitudinally edges 12 for aiding in the correct positioning of the razor 12- thereon. 7

From the foregoing it will be readily seen that by my invention I provide a safety razor embodying all the qualities inherent to a hollow ground razor, it being a well known fact that a razor of the latter pattern insures a much more effective and comfortable shave than a thin sheet blade gives, therefore the numerous advantages accruing to my struc ture of safety razor will be clearly understood without further explanation, while its use and adjustment to give easy or close shaves are self-evident.

Finally I wish it understood that while I have shown and described the best form at present known to me, my invention is susceptible of modification, and it is intended hereby to include all such variations thereof that may reasonably be construed as falling within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is flat spring longitudinally disposed between the combed flanges the ends whereof are turned and centrally notched, means for holding said flat spring in place, a razor having opposed hollow-ground blades adapted to seat on the aforesaid combed flanges, ribs central of said razor for cooperation with the centrally notched ends of the flat spring, and means for adjustably connecting the razor and handle portion in operative position.

2. A safety razor'comprising a tubular handle portion having opposed outwardly curving combed flanges at one end, a flexed flat spring longitudinally disposed between the combed flanges the ends whereof are turned and centrally notched, means for holding said flat spring in place, a razor having opposed hollow-ground blades adapted to seat on the aforesaid combed flanges, ribs central of said razor for cooperation with the centrally notched ends of the flat spring, and a rotatable stem axially central of the tubular handle having threaded connection into the razor for varying the cut of the device.

In testimony whereof I alflx my signature.

ALEXANDER T. STEWART.
